Edward Andrews was an incredibly prolific TV actor in the 1950s-70s. He normally played somewhat stiff and stodgy middle-aged businessmen. However, here he's given a great opportunity to play something different...and it makes for a wonderful installment of "Thriller"!
In "A Good Imagination", Frank Logan (Andrews) is a successful book seller who is married to a cheating woman (Patricia Barry). When the show begins, he bludgeons one of her lovers to death. But, like potato chips, he cannot stop with just one. Soon, this normal looking guy is killing others...and he seems to be having a terrific time doing it. In fact, it makes this show a bit like a dark comedy because he is so clever and enjoys himself so much!
This was a most enjoyable installment in this normally mediocre series...thanks to Andrews terrific acting and a lovely script by Robert Bloch...the same man who wrote "Psycho" and many other thrilling tales.
